Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2024-09-11T14:18Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: -1 (unspecified) Note: Characterized by two consecutive enhancements in magnetic field components, the first at 2024-09-11T14:18Z (B_t: 3.5nT to 9.15nT, B_y: -1.2nT to -8.1nT, B_z: 1.46nT to 5.94nT) and the second at 2024-09-11T15:40Z (B_y: -4.29nT to 9.61nT, B_t: 3.19nT to 10.32nT). Enhancements in solar wind speed (approx. 343 km/s to approx. 390 km/s), temperature (approx. 26kK to approx. 70 kK), and density (approx. 4 p/cc to approx. 24 p/cc). These enhancements are possibly due to the arrival of CME: 2024-09-08T01:36Z, which arrived at STEREO A at 2024-09-10T21:00Z. However, this arrival at L1 is more delayed than initially modeled for this CME, therefore analysis to confirm the arrival candidate is still ongoing.
